401

Data not found​ This error occurs when the requested data cannot be found, which may be due to a faulty or incorrectly entered domain (e.g., 'fsdfsdfdsf.com' or 'CNN.COM' instead of 'cnn.com').

Double-check the domain name for accuracy. Ensure it is entered correctly and in the proper format (e.g., lowercase for domains and without additional paths like '/sports').

403

Invalid API key / No Credits​ This error is triggered when the API key used is invalid or your account has run out of data credits.

Visit the API management page on the Similarweb platform to verify your API key and check the remaining data credits. Ensure your key is correctly entered and your account has sufficient credits.

Reduce the frequency of your requests to stay within the limits. Consider spacing out your requests or implementing a rate limiter to avoid this error.

Review the API documentation to verify the supported granularity levels and adjust your request to match these specifications.
